Chapter 2 Test

Question 1

Particles Are always ______+________

Answer 1

Moving and have attraction

Question 2

Shape and Volume of solids, liquids, and gases

Answer 2

Solids have both definite shape and volume.
Liquids only have a definite volume
Gases don’t have any definite shape or volume

Question 3

Why Gas Volume can change

Answer 3

Gas molecules can expand to fill it’s container

Question 4

Why can a basketball bounce high?

Answer 4

The basketball is under pressure and while the ball is bouncing the molecules are forced to hit each other.

Question 5

Charle’s and Boyle’s Law

Answer 5

Charle’s Law is when the Temperature is rising the volume is also rising, the pressure stays the same.
Boyle’s Law is when the Volume is going down the pressure is going up, the temperature stays the same.

Question 6

Two Types of Solids

Answer 6

Crystalline is when the molecules are neat and ordered

Amorphous is when the molecules aren’t neat

Question 7

Speed and Movement/Attraction of Solids, Liquids, and gases

Answer 7

Solids vibrate are slow and have a lot of attraction
Liquids slide past each other have a medium speed and have a medium attraction
Gases fly around are really fast and the molecules have little attraction to each other

Question 8

Balloon and sun

Answer 8

The balloon would expand because of Charle’s Law

The molecules would keep on expanding and the material of the balloon wouldn’t be able to withstand the pressure.

Question 9

Classify Endo/Exo phase changes

Answer 9

Endo- Melting (Solid to Liquid), Vaporization (Liquid to Gas)
Sublimation (solid to a gas)
Exo- Freezing (Liquid to solid), Condensation (Gas to Liquid), Deposition (Gas to Solid)

Question 10

Rank the speeds of a solid liquid and gas

Answer 10

1) Gas
2) Liquid
3) Solid
